With Type 1 precision this meter is ideal for almost any noise
monitoring application. As well as the usual "broadband"
A weighted measurements, it has built in octave band filters. The
filters scan automatically and repeatedly to built up a full spectrum
of the noise, split into the 10 octave bands.

The Model 83 stores all broadband and octave band measurements in its internal memory. The measurements can be downloadad using the Analyzer software that is included with the meter.

Simple and Quick

Just calibrate, press Start, wait for the level to settle, press Stop. At any time you can read both the LAeq and the LCPeak from
the large backlit display. You can even switch off, return to your office,
switch on and recall the last measurement made.
